You may need to use the appropriate technology to answer this question. Bob Feller, an Iowa farmer, has recorded the daily high temperatures during the same five-day stretch in May over the past five years. Bob is interested in whether this data suggests that the daily high temperature obeys a normal distribution. Use a = 0.01 and conduct a goodness of fit test using 5 classes to see whether the following sample appears to have been selected from a normal probability distribution. (Note: x= 70 and s= 17.) 53 84 92 56 53 93 53 50 67 93 88 63 85 53 55 96 56 77 90 60 57 86 88 State the null and alternative hypotheses. O Ho: The population has a normal probability distribution. H: The population has a sampling mean distribution. Ho: The population has a normal probability distribution. H: The population does not have a normal probability distribution. O Ho: The population has a normal probability distribution. H₂: The population has a x² distribution. O Ho: The population does not have a normal probability distribution. H: The population has a normal probability distribution. Find the value of the test statistic. 7.6 x Find the p-value. (Round your answer to four decimal places.) p-value=0.0224 x 48 54 State your conclusion. O Do not reject Ho. We conclude that the population has a normal probability distribution. O Reject Ho. We conclude that the population does not have a normal probability distribution. • Reject Ho. We conclude that the population has a normal probability distribution. O Do not reject Ho- We conclude that the population does not have a normal probability distribution.
